Installed wntr in virtual environment using pip.

It looks like you're using Python 3.10 which WNTR does not currently support. We can try to include the build for 3.10 in the next release.

I saw the same error message and my Python is 3.9.7. Please see message below. I had recently updated the WNTR package and I wasn't having this issue in the past.

@terrahaxton, How did you update WNTR (git pull, pip, conda)? Also, do you have a Python 3.9 windows build of the evaluator in the wntr\sim\aml folder? The file would be called _evaluator.cp39-win_amd64.pyd.

[terrahaxton]

@kaklise I updated WNTR using git pull and then ran python setup.py develop. No, I don't have the file by the name you listed. Here are the files in the wntr\sim\aml folder

[kaklise]

@terrahaxton, was this issue resolved when you pull from the main branch?

[Thaulino]

I am running python 10 and had some trouble but it is not an issue because as far as i know python 10 is currently not supported but will be with the next major release. i left this comment as i am not knowing how to delete it

[terrahaxton]

@terrahaxton, was this issue resolved when you pull from the main branch?

@kaklise Yes, this issue was resolved when I pulled from the main branch. Thanks!

[kaklise]

Closing this ticket and referencing #254. We hope to support Python 3.10 soon.

having challenges to. just installed the complete package and gettint the wntr error. pleas who can assist. Thanks

[kaklise]

The WNTR repository no longer contains the prebuilt binaries. If you clone the repository, you need to build it using --build option, see https://wntr.readthedocs.io/en/latest/installation.html#developer-instructions. If you install through pip, the binaries are packaged.

I don't see an error related to wntr.sim.aml._evaluator in the traceback. It looks like you're using DHALSIM, which I believe uses Python 2.7 and 3.8. I'm not sure if that is causing the issue. We recently push a change to WNTR that adds the --build option to setup.py by default. This will build the evaluator module if you need to clone and build WNTR.

Are you suggesting I install WNTR on the machine. Not very good in Linux. Please be more specific. Thnaks

[kaklise]

I'm not sure what the issue is. If you need to add the evaluator module, you can build WNTR using the instructions at https://wntr.readthedocs.io/en/latest/installation.html#developer-instructions. Our team has used DHALSIM in the past and I believe the install process with WNTR was fine. @dbhart, any advice based on traceback?
